One Calendar Month Notice Period

[perry]

Hi,

Please could an expert help me to understand the definition of a "calendar month".
The office where I work closes on 15 December 2016 and reopens on 5 January 2017 (ie. employees are required to take 10 days of their annual leave during this period).
My contract states that my notice period is "one calendar month". If I resign on 15 December 2016, would this be effective 1 February 2017? Would January be seen as one calendar month, even though the office is not open for the 2nd,3rd and 4th of January? Otherwise do I need to wait until February to resign?

Thanks

If by that you mean your last working day would be 31st January, then Yes.

Would January be seen as one calendar month, even though the office is not open for the 2nd,3rd and 4th of January?

Yes.
